I would start by removing the carb for a strip and thorough clean. There are some tiny drillings in the jet block and carb throat that can be poked through with fuse wire and air line, which will require the jet block to be removed. Also take the float bowl apart for a good blow through. Ron

Magneto problems are often condensor related and in my experience take a bit more warming up before they give trouble.

Could it be choke related, is the choke slide fully lifting?

That's a good point Rob. Are you pulling the choke lever off? ie lifting the slide? Ron
